[CMake] CMake Visual Studio 64bit flag?

[aaron.meadows at thomsonreuters.com]

Seems to work correctly from my tests:

 

CMakeLists.txt:

cmake_minimum_required (VERSION 2.8)

 

project(test CXX)

message( STATUS "CMAKE_GENERATOR: ${CMAKE_GENERATOR}")

message( STATUS "CMAKE_CL_64: ${CMAKE_CL_64}")

 

 

 

c:\dev2\Builds\test\x64>cmake -G "Visual Studio 8 2005" ../.

-- Check for working CXX compiler using: Visual Studio 8 2005

-- Check for working CXX compiler using: Visual Studio 8 2005 -- works

-- Detecting CXX compiler ABI info

-- Detecting CXX compiler ABI info - done

-- CMAKE_GENERATOR: Visual Studio 8 2005

-- CMAKE_CL_64: 0

-- Configuring done

-- Generating done

-- Build files have been written to: C:/dev2/Builds/test/x64

 

 

c:\dev2\Builds\test\x86>cmake -G "Visual Studio 8 2005 Win64" ../.

-- Check for working CXX compiler using: Visual Studio 8 2005 Win64

-- CMAKE_CL_64: 1

IIRC that doesn't work if you use the Studio generator (i.e. not
Makefiles). So 

this needs to be something like "if (CMAKE_CL_64 or CMAKE_GENERATOR
MATCHES 

Win64)"
